Map XML: Store camera position. Stopped using DTDs (because they make it too hard to change the XML structure without breaking all the old XML files). Game.h: Include fewer files, to make compilation sometimes faster. World: Changed some things to not be singletons, since they were (ab)used as CWorld members. This was SVN commit r3670.
